I do not know whether this is of any use but I had both a hum (probably 50Hz or derivative) on both channels and a high level whistle on the right channel - these were constant level. I was using the SB3 directly from its analogue outputs into my electronic x-overs / amplifiers into my Linkwitz Orions. The solution (for me) was to change from the walwart to a Power One linear psu - since then no noises - even when listening through my Stax Lambda-Pro/SRM-1 setup. I know the issue of psu's has been contentious and I can only add that this worked for me in removing the noise in my system - no comments on better/worse sound.
